WebFor example, the major groups of marine animals such as mollusks and arthropods appeared for the first time about 541 million years ago at the base of the Cambrian Period of the Phanerozoic Eon. WebThe theory of evolution is supported by instances of direct observation, the existence of homologies and fossils, and certain biogeographical patterns. Key points: Evidence for large-scale evolution ( macroevolution) comes from anatomy and embryology, molecular biology, biogeography, and fossils.

WebT he first life on Earth began more than 3.8 billion years ago with individual cells that did not contain nuclei, known as prokaryotes. These first living cells were heterotrophs, meaning that they were dependent on external nutrition sources. Today's heterotrophs include all animals and some fungi that ingest or absorb food from their environment.
